iSound NL200 NearLink Wireless Microphone System, 2.4G SLE, 30m, DSP Receiver

Wireless speech capture without the wireless headaches. The iSound NL200 is a NearLink microphone system: its 2.4 GHz NearLink SLE link carries 48 kHz/16-bit audio with 0.25 ms latency - a twentieth of Bluetooth's - across a 30 m line-of-sight range, with AES-128 encryption and adaptive frequency hopping keeping the channel clean in crowded RF environments. The featherweight 10.5 g transmitter pucks wear as a lavalier or magnetic headworn mic and run 4+ hours per charge; the fast-charging case refills them more than three times over. On the wall, the 86-type receiver's DSP chain (acoustic feedback cancellation, AGC, adaptive noise suppression, room acoustic calibration) hands clean speech to the room over UAC digital or balanced/unbalanced analog outputs. Any mic pairs with any receiver over NFC, and multi-room deployments run crosstalk-free - one mic per lecturer keeps classrooms clean and hygienic.
